Scientists have finally invented a time-space shuttle. In order to prevent someone from using it to go back to the past and change history, a team called the time-space special police was established, and Max (Jean-Claude Van Damme) is one of them. Ten years ago, Max's wife Melissa (Mia Sara) died, and the murderer has not been caught yet, which has become Max's heart knot. Max is determined to use the time-space shuttle to investigate the truth of the incident. When he returns to the past, he learns that the man behind the scenes is a congressman named McColm (Malcolm Stewart), but this person has a very complicated background, and Max can't do anything about him. Policewoman Fielding (Gloria Reuben) becomes Max's partner and follows him back to 1994 to catch McColm. Who knows that Fielding's true identity is actually McColm's minions, and Max's plan fails again.
